This gorgeous Porsche 550 Spyder had just three owners, and had covered just 10,500 miles on it from new. Seinfeld said of it: "You can’t drive a sonnet by Shakespeare or a symphony by Beethoven. But this would be the automotive equivalent." It sold for $5,335,000 (approx £3,780,000).

Little do most people know that Porsche was producing utility vehicles long before the Cayenne.

This example, thought to be the last ever produced, sold for $330,000 (around £234,000).

This gorgeous Porsche 356B was a rare 2000GS, or Carrera 2, model, which featured an uprated 2.0-litre four-cam engine designed for greater mid-range torque. One of 300 built, it sold for $825,000 (£585,000).

A detailed racing history made Seinfeld's Porsche 718 RSK a real joy. In-period drivers included Roger Penske and Lake Underwood, and the car had undergone a full restoration by Porsche specialist Joe Cavaglieri. It sold for $2,860,000 (approx £2,000,000).

A Porsche 917 always provokes excitement, especially one as meticulously restored as this one. Finished in Penske Racing's 1973 Sunoco livery, this 917/30 was one of six produced, and sold for $3,000,000 (around £2,100,000).

The "Flachbau" ("flat nose") 911 Turbos might have looked odd, but with only 74 made, they've become real collectors' items. As Seinfeld himself said: "The sound this car makes at about 6,000 rpm out of those hand-formed fender vents is worth whatever this one costs. So weird, so cool, so rare." This one sold for $1,017,500 (around £720,000).

Everybody recognises the classic shape of the VW Camper, but this one was pretty special in that it was in immaculate, original, unrestored condition.

“This is as pure and perfect a ’60s 911 as there is in the world. The colors are so wonderful. No restored car has this delicious smell. Car heaven as a pure early 911.” So said Mr Seinfeld, and frankly, we couldn't have put it better ourselves. This beautiful 911 sold for $275,000 (around £200,000).

Having been owned by one family for 50 years and regularly exhibited at shows where it won numerous trophies, there were few examples of the Porsche 356 quite like this 356A Speedster. It sold for $682,000 (approx £480,000).

Seinfeld was already saying that he regretted selling this VW Beetle even before the auction, so special was it. Originally owned by a schoolteacher from South Dakota, this cute Beetle was one of the last 36bhp examples and had less than 15,500 miles on the clock. It went for $121,000 (around £86,000).

An exceedingly rare Carrera Speedster GS finished with aluminium panels, and the only one to have been painted in Auratium Green, this 356A was one of a kind. It sold for $1,540,000 (approx £1,100,000).

One of a run of racing 911s commissioned by Roger Penske for his International Race Of Champions (IROC) series, this Carrera 3.0 IROC RSR, to give it its full title, was campaigned by Peter Revson and finished 3rd in the inaugural race at Riverside International Raceway in California. It went under the hammer for $2,310,000 (around £1,600,000).

We'll let Seinfeld himself explain why he owned this classic Speedster: “One of my favorite 911s and another of the greatest summer cars of all time. I like the Star Wars Storm Trooper look with a snazzy low-cut top. I’ve had five different ’89 Speedsters over the years in different colors. Loved every one. This one is cool because it doesn’t have A/C. Lighter.” It sold for $363,000 (approx £257,554).

Only 356 examples of the 997 Speedster were produced, and this example, wearing just 5,000 miles on the clock, had been owned from new by Seinfeld. It sold for $440,000 (around £310,000).

This Carrera GT was one of two prototypes produced, and was used for all the pre-production press photography with Bernd Schneider at the wheel. It was the only car in the collection that didn't sell, probably on account of the fact that it wasn't actually usable.
